Key Concepts

Probability Density Function (pdf)

A probability density function describes the relative likelihood for a continuous random variable to take on a given value. It is used to define the probability of the variable falling within a particular interval, and the integral of the pdf over that interval gives the probability of the variable being in that range.

Continuous Random Variables

Continuous random variables are those that can take any value within a given range. Instead of summing probabilities for individual outcomes, probabilities are calculated by integrating the density function over the required interval.

Conditional Probability

Conditional probability is the calculation of the probability of an event occurring, given that another event has already occurred. In the context of continuous distributions, it involves computing the ratio of the integral of the density function over the intersection of the two events to the integral over the condition event's range.

Integration in Probability

Integration in probability is the process used to calculate the probabilities associated with continuous random variables. It involves integrating the probability density function over the desired interval, which yields the probability that the random variable falls within that interval.
